UNITED STATES ADELARD COUTURE. OF WARREN RHO'DE ISLAND.

OIL BURNER.

Application filed July 28.

T all whom it may concern.

Be it known that I. ADELARD CoUrUnE. a citizen of the United States.residing at \Varren. in the county of Bristol and State of Rhode Island.have invented new and useful Improvements in Oil Burners. of which thetollowing is a specification.

This invention relates to certain new and uset'ul improvemen s in oilburners and the primary object of the invention is to provide means forautomatically efl'ecting stoppage of the oil supply to the burner uponfailure of suflicient supply of current to ett'ect proper operation ofthe motor.

A further object of the invention is to provide means for causinginitial manual starting of the motor and then further manual operationto set the motor for automatic stoppage in event of the current failure.

A still further object of the invention is to provide improved means forfeeding the oil to the burner and for efiecting consumption with maximumheat and for also utilizing the oil to lubricate the various movingparts of the apparatus.

Another object of the invention is to provide an improved oil burnerstructure and air feeding and diverting means therefor.

In the drawings':

Figure 1, is a top plan view of the invention;

Figure 2, is a side elevation. partly broken away;

Figure 3 is an enlarged section on line 33 of Figure 1;

Figure 4, is a top plan view of the interior of the governor andelectrical control device;

Figure 5, is an enlarged section on line -5 of Figure 1.

In proceeding in accordance with the present invention a base or bed 1is employed and upon which the invention is mounted, including a motor2, and a housing 3 for the governor and electrical control device, arotar pump 4 being connectedvto the housing 3. A drive shaft 5 isdriven'bv the motor and has a governor 6 mounted' thereon, (Fig. 4.)worm gear 7 is mounted on the drive shaft 5 and meshes with a worm gear8 on a vertical shaft 9, the latter being mounted in ball bearings 10and 11 carried b a burner casing '12.

The casing 12 is ollow and formed to receive oil in which the worm ears7 and 8 are submerged, the oil level icing indionto the plate 16, thepipe 17 1923. Serial No. 654,428.

cated at and controlled by an overflow pipe 13.

A fan 14 is mounted on the shaft 9 and above the fanis located acup-shaped air dive'rter 15. he latter being stationarily secured withinthe casing top 12' of the burn-. er and having a peripheral series ofspaced inclined blades or plates 15 extending between the rim of thediverter and the walls of casing top 12. A perforated plate 16 iscarried by the shaft 9 andisf; located above the air diverter 15. Avertical pipe 17 has a discharge 18 from which flatter oil drips havinga hori-. zontal part 19 connected 110 the pump 4. The oil after passingthrough the pump is controlled by a valve 20, the stem 22 of which isconnected to a diaphragm 23 and is tensioned by a coil spring 24, all ofthe parts being mounted in a casing 25, the latter having a steam pipe26 leading from the boiler (not shown) into the upper end of the casingabove the diaphragm.

The oil of the burner is also utilized to lubricate the movable partsand accordingly, and as 'shown in Figure 3 a conducting pipe 27 conveysthe oil into the retaining cup 28 of the ball bearing 11, from which theoil gravitates into the lower part of the burner casing 12. where theoil is maintained at the level 0 by the overflow pipe 13.

A pressure valve located in the pipe 19 also controls the oil after itpasses the pump 4, and is connected by a branch 21 to the overflow pipe13. A pipe conducts oil from the overflow pipe 13 to the motor housing3.

The motor control switch is shown in Figure 4 and includes a feed wire30, and a switch 31, which latter in one position contacts with point 32which connects to a wire 33 leading to the motor and from the latter thecurrent passes out through a wire 34, thus causing operation of themotor. Upon throwing of the switch 31, to contact 35, the current willbe diverted and will pass from the wire 30 and through a wire 36 to aspring arm 37 and through a conductive disk 38 connected to the governor6. From the disk 38, the current passes to a spring arm 39, the latterconnected by a wire 33 to the motor. The disk 38 assumes a position inengagement with the spring arms 37 and, 39, when the normal speed of themotor causes the governor 6 to move the disk to the position depicted inFigure 4 of the drawings.

The casing 12 has air inlets 40 located beneath the fan.

In operation, the switch 31 is first turned to engage contact 32 tocause the current to flow through the motor 2 by passing through thewire 33, setting up operation of the gov ernor, and thereby causing disk38 to engage contact fingers 37 and 39, after which the switch is turnedto divert the current so that it passes through the disk of the overnorin passing through the motor. Should therefore. for any reason, theelectric supply be cut-off, the disk, will, due to the inoperation ofthe motor move out of engagement with the contact fingers 39 and 37 andcannot be again started except through manual movement of the switch, asabove described.

The operation of the motor, effects rotation of the shaft 9 and therebyfan 14, which causes air to be drawn into the burner casing 12 throughthe ports 40, the air then passing upwardly between the diverter bladesand being forced through the perforations of the plate 16, and at thesame time operates the oil pump 4 to cause a flow of oil to the burnerand to the bearings as described.

Having thus described my invention, what I claim as new and desire tosecure byLet ters Patent is 1. In an oil burner, a casing having airinlets, a horizontal fan above the inlets, a stationary air diverterdevice located above the fan, a horizontal rotary perforated plate abovethe air diverter, means to rotate the fan and plate, and means to supplyoil to the to of the plate, said air diverter device including aperipheral series of spaced plates extending in a substantially verticalplane and disposed between the periphery of the air diverter and thewalls of the eas- 2. In an oil burner, a casing having air inlets, afixed air diverter in the casing, spaced blades between the diverter andthe inner face of the casing forming substantially vertical passagesopen at their upper and lower ends, a rotary perforated oil receivingmember above the diverter and blades, and a fan beneath the diverter,means to supply oil to the top of the oil receiving member. and means torotate the fan and said member.

Ir an oil burner, a casing having air inlets, a fixed air diverter inthe casing, spaced curved blades between the diverter and the inner faceof the casing forming substantially vertical passages open at theirupper and lower ends, a rotary perforated oil receiving member above thediverter and blades, and a fan beneath the diverter, means to supply oilto the top of the oil receiving member and means to rotate the fan andsaid mem er.

4. In an oil burner, oil burner means including a rotary member, anelectric motor for driving said member, a governor operated by themotor, asource of electrical supply, manual control means for the motor,means to electrically connect the source of supply to the motor,governor and said manual means whereby upon initial movement of saidmanual means in one direction the latter will pass the current directlythrough the motor to start same and upon a second movement in adifferent direction will subsequently divert the current to cause sam topass through the governor and then the motor and means whereby uponfailure of the current supply the governor will break the electricalconnection to the motor and stop the latter thereby to require saidinitial movement of the manual means to restart the motor.

5. In an oil burner, oil burner means including a rotary member, anelectric motor for driving said member, a governor operated by themotor, a source of electrical supply, a switch for the motor, means toelectrically connect the source of supply, the motor, governor and saidswitch whereby upon initial movement of said switch in one direction thelatter will pass the current directly through the motor to start sameand upon a second movement in a difierent direction will subsequentlydivert the current to cause same to pass through the governor and thenthe motor, and means whereby upon failure of the current supply thegovernor will break the electrical connection to the motor and stop thelatter thereby to require said initial movement of the switch to restartthe motor.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
